Anatomy

The ligament of Treitz is comprised of two parts, the first of which passes from the right crus of the diaphragm to connective tissue surrounding the coeliac artery. The second, muscular, part descends from said connective tissue to the duodenum, between the pancreas and the left renal vein. It is the second part that actually suspends the duodenojejunal flexure. 1
